Jingangzhuo – Carving Eternal Luxury with Artisan Spirit
Established in 2020, Jingangzhuo Jewelry is a vertically integrated fine jewelry enterprise specializing in jewelry design and development, precious metal casting, gemstone cutting and processing, advanced setting craftsmanship, and direct-to-consumer sales. Based in China's jewelry manufacturing hub, we uphold the philosophy of "Crafting Timeless Treasures with Artisan Precision", dedicated to delivering high-quality, cost-effective bespoke jewelry services to clients worldwide.
Production Capabilities & Industrial Layout
Our 1,000+ square meter modern jewelry factory is equipped with precision casting machines, CNC laser engravers, Italian micro-setting systems, and other advanced tools, enabling end-to-end in-house production from 3D design modeling and wax carving to metal forming and gemstone setting. In 2021, to enhance quality control at the source, we established a dedicated gem processing center. By integrating Belgian Antwerp diamond-cutting techniques, we now independently execute 12 complex cuts including emerald and radiant shapes. This completes our closed-loop system spanning "raw material sourcing – precision gem processing – jewelry manufacturing – direct sales," significantly reducing lead times and intermediary costs. We offer luxury-grade jewelry at 30%-50% below market prices.
